根據(ju)棒(bang)(bang)(bang)球規則的(de)(de)規定,球棒(bang)(bang)(bang)必(bi)須(xu)為(wei)平滑之(zhi)(zhi)(zhi)圓型棒(bang)(bang)(bang),最(zui)粗的(de)(de)部(bu)(bu)分直(zhi)徑不(bu)得大於(wu)2.75英(ying)(ying)(ying)吋(cun)(cun)(七(qi)公(gong)分),長(chang)度(du)(du)不(bu)得超過42英(ying)(ying)(ying)吋(cun)(cun)(106.7公(gong)分),須(xu)用(yong)(yong)一(yi)根木材(cai)制(zhi)成(cheng)(cheng)。以(yi)合成(cheng)(cheng)方(fang)式(shi)制(zhi)造之(zhi)(zhi)(zhi)球棒(bang)(bang)(bang),在沒有獲(huo)得比(bi)(bi)賽主(zhu)(zhu)(zhu)辦(ban)單(dan)(dan)位認(ren)可(ke)之(zhi)(zhi)(zhi)前,於(wu)正式(shi)比(bi)(bi)賽中(zhong)不(bu)得使(shi)用(yong)(yong)。由金屬(shu)、木片或竹片接合制(zhi)成(cheng)(cheng)之(zhi)(zhi)(zhi)球棒(bang)(bang)(bang),如(ru)果獲(huo)得比(bi)(bi)賽主(zhu)(zhu)(zhu)辦(ban)單(dan)(dan)位認(ren)可(ke),則準予使(shi)用(yong)(yong)。球棒(bang)(bang)(bang)凹(ao)頭的(de)(de)部(bu)(bu)分,深度(du)(du)必(bi)須(xu)在一(yi)英(ying)(ying)(ying)吋(cun)(cun)(2.54公(gong)分)之(zhi)(zhi)(zhi)內(nei),寬度(du)(du)不(bu)得超過兩(liang)英(ying)(ying)(ying)吋(cun)(cun)及小(xiao)於(wu)一(yi)英(ying)(ying)(ying)吋(cun)(cun)(5.08公(gong)分~2.54公(gong)分)。凹(ao)狀(zhuang)(zhuang)部(bu)(bu)分直(zhi)徑必(bi)須(xu)為(wei)曲線狀(zhuang)(zhuang),不(bu)可(ke)以(yi)附(fu)著(zhu)(zhu)其他任何(he)物(wu)質(zhi)。球棒(bang)(bang)(bang)的(de)(de)握(wo)把位不(bu)得超過18英(ying)(ying)(ying)吋(cun)(cun)(從棒(bang)(bang)(bang)端起45.72公(gong)分以(yi)內(nei)),握(wo)把部(bu)(bu)分得包扎或使(shi)用(yong)(yong)任何(he)材(cai)料處(chu)理(包括用(yong)(yong)松脂等)使(shi)適合掌握(wo),但任何(he)使(shi)用(yong)(yong)之(zhi)(zhi)(zhi)村料包括松PINE TAR),裁(cai)判員認(ren)為(wei)有超越18英(ying)(ying)(ying)吋(cun)(cun)之(zhi)(zhi)(zhi)限制(zhi),則該球棒(bang)(bang)(bang)於(wu)比(bi)(bi)賽時不(bu)得使(shi)用(yong)(yong)。非經比(bi)(bi)賽主(zhu)(zhu)(zhu)辦(ban)單(dan)(dan)位之(zhi)(zhi)(zhi)認(ren)可(ke),於(wu)比(bi)(bi)賽中(zhong)不(bu)得使(shi)用(yong)(yong)著(zhu)(zhu)色球棒(bang)(bang)(bang)。
復合(he)(he)(he)球(qiu)棒(bang)(bang)(bang)(bang)的(de)(de)(de)(de)(de)材(cai)質(zhi)為(wei)白楊木(mu)(mu)(mu)、楓木(mu)(mu)(mu)與竹片聚合(he)(he)(he)壓(ya)縮(suo)而(er)成,也有人稱之為(wei)「壓(ya)縮(suo)棒(bang)(bang)(bang)(bang)」、「合(he)(he)(he)成棒(bang)(bang)(bang)(bang)」、甚至「竹棒(bang)(bang)(bang)(bang)」。由於復合(he)(he)(he)球(qiu)棒(bang)(bang)(bang)(bang)融合(he)(he)(he)了木(mu)(mu)(mu)棒(bang)(bang)(bang)(bang)與鋁(lv)棒(bang)(bang)(bang)(bang)的(de)(de)(de)(de)(de)優點,彈(dan)性較佳而(er)且不易(yi)斷裂(lie),揮擊時的(de)(de)(de)(de)(de)力道(dao)其實不會輸給鋁(lv)棒(bang)(bang)(bang)(bang),所以在一般國(guo)(guo)際(ji)正式(shi)比(bi)(bi)賽(sai)場(chang)合(he)(he)(he),通常都是(shi)不被允許使(shi)用(yong)的(de)(de)(de)(de)(de);不過由於國(guo)(guo)際(ji)棒(bang)(bang)(bang)(bang)球(qiu)總(zong)會積(ji)極推展國(guo)(guo)際(ji)賽(sai)事全面改用(yong)木(mu)(mu)(mu)棒(bang)(bang)(bang)(bang)的(de)(de)(de)(de)(de)政策之下,復合(he)(he)(he)球(qiu)棒(bang)(bang)(bang)(bang)已(yi)經(jing)被視為(wei)全面改用(yong)木(mu)(mu)(mu)棒(bang)(bang)(bang)(bang)前的(de)(de)(de)(de)(de)過渡(du)球(qiu)棒(bang)(bang)(bang)(bang),在國(guo)(guo)內三(san)級棒(bang)(bang)(bang)(bang)球(qiu)比(bi)(bi)賽(sai)中,球(qiu)棒(bang)(bang)(bang)(bang)當(dang)然(ran)不可能是(shi)純「鋁(lv)」所制成,通常是(shi)以合(he)(he)(he)金成份為(wei)主。鋁(lv)棒(bang)(bang)(bang)(bang)的(de)(de)(de)(de)(de)使(shi)用(yong)已(yi)經(jing)日(ri)漸式(shi)微,在重要的(de)(de)(de)(de)(de)國(guo)(guo)際(ji)比(bi)(bi)賽(sai)當(dang)中,幾乎已(yi)經(jing)看不到了;在國(guo)(guo)內的(de)(de)(de)(de)(de)三(san)級棒(bang)(bang)(bang)(bang)球(qiu)比(bi)(bi)賽(sai)中,有時仍然(ran)看得到鋁(lv)棒(bang)(bang)(bang)(bang)的(de)(de)(de)(de)(de)身影。
1.若(ruo)材(cai)質強度(du)高(gao) - 硬度(du)/韌性高(gao),傳到(dao)球的力(li)道較直接,能量損(sun)耗較少,此(ci)謂棒(bang)子的彈性系數高(gao);
2.擇(ze)材質(zhi)彈性低 - 較硬的東西,就比較不那么flexible,而(er)且回到手掌的震(zhen)動較大,這可以理(li)解;
3.在此同時 - 棒子比(bi)較(jiao)耐用(yong)不易斷。
球(qiu) 棒木質不比手套皮(pi)革嬌(jiao)嫩,倒是木、竹材(cai)質都怕濕(shi)(shi),保持干爽的(de)細節要注(zhu)意。新棒會上(shang)漆(qi),不只是印(yin)logo、討個亮麗外觀(guan),主要能防(fang)濕(shi)(shi)氣,如同所有木制品(pin)一般。球(qiu)棒打久會磨(mo)擦掉漆(qi),此(ci)時更應該注(zhu)意保存(cun)時的(de)防(fang)濕(shi)(shi)。
